SPECIFICATION forming part of Letters Patent No. 641,942, dated January 23, 1900.

Application tiled January lO, 1899. Serial No. 701,751. (No madcl' To all whom t may concern,.-

le it known that .'we, WILLIAM J. DON- ALDSON and OYRUS BQRGNER, citizens of the United States, and residents of Philadelphia, Pennsylyania, have invented certain '15 a perspective view of part of a wall constructed in accordance with our invention. Fig. 2 is a vertical section of the same on the line w w, Fig. l'. Fig. 3 is a section on the line a; x, Fig. 1. Fig. i is a rear view, on an zo enlarged scale, of one of the facing-blocks for the wall. Fig. 5 is a section of the same ou rthe line yy, Fig. 4; and Fig. 6 is a view illustrating another form of block constructed in accordance with our invention.. I n carrying out cur invention we contemplate the use of molde-d blocks of artificial stone or cement permanently and rigidly secured to the wall or partition structure, these blocks as to their exposed faces being ornamented in any desired way, `depending upon the architectural character of the building which isbeing erected.

In the drawings, l l represent vertical beams of the wall structure, which in the 3 5 present instance are shown as metal I-beams,

hntfwhich may be beams', posts, or joists of woodor other. available material capable of use for the framework of the building. To the outer sides of these beams is secured by .1o wiring or in any other'available manner metallic sheathing 2, which, as shown in the drawings, is of the character known as expanded metal, although wire-netting, perforated sheet metal, laths, or other desired 45 form ofvsheathing may be employed.

The facing-blocks 3 are molded in any desired size or shape, depending upon the archi# tectural requirements ofthe building, and embedded in each of theselblocks is a struc- 5o ture to which may be' secured wires Il of such masses ot' plaster may be omitted;

length that the ends vof the wires will project considerably beyond the rear face of the block, as shown, for instance, in Figsand 6.

The character of the embedded structure may vary without departing from our inveution. For instance, in the block shown in Fig. 4 itconsists of a seriesof rods 5,'around which the wires are wrapped, so as to secure them thereto, while in the block shown in Fig. 6 the embedded 4structure consists of a sheetv of expanded metal of the same character asy is used forthe sheathing of the wall.'

The projecting wires et of the blocks-3 pr'ovide a ready means for securing said blocks l to the sheathing 2 in their proper relative po 65 sitious, the projecting ends of the wires being passed through the meshes of the sheath-- img` and then twisted on the inner side of the same, as shown in Figs. 2 and 3.

When metallic sheathing 'is employed,l theA 7o 'same should be protected from the air in order to prevent deterioration due to oxidation, Hence We prefer to embed the same in plaster or cement, which also serves as a means of securely uniting the facingblocks 75 t0 the wall.

' As shown in Figs.'1, 2, and 3, a thin layer of cement or plaster ''is spread over the metal sheathing before the application of the surf face-blocks 3, the latter being set in position while this layer of' plaster or'cement is still plastic, so that they will firmly adhere thereto, the projecting' wires 4 passing through the plaster for engagement with the metallic sheathing behind the same. We also prefer to apply a layer of plaster 8 tothe inner side of the metallic sheathing, this plaster being applied while the outer layer 7 is still' plastic, so that the inner and outerlayers of plaster extend through the meshes of the'metallic sheathing and unite one with theother, so as to forma bodybf vplaster or cement completely enveloping' the metallic sheathing,

and consequently having' a firm held thereupon. In some cases one or the other o these ut we prefer'to employ both on account of the greater durability of the structure lthereby secured. Metallic sheathing 9 is also applied to theiuner faces of the beams 1, and cement me Uniilvni U i' pgwiiion eensisuing oi beams. thereon, :imi MCing-blois i having s i having.; si
